ZIndexedGroupView

@objcMemberspublicfinalclassZIndexedGroupView:UIView

UIView which only holds views that conform to ZIndexedView, where views are ordered in the
subview list by their zIndex property. This causes each view to be rendered and hit-tested inside
ZIndexedGroupView based on their zIndex.

Note

All views should be added via upsertView(:). Using any other insertion method
on this class may have adverse effects. Adding any view other than one that conforms to
ZIndexedView will result in an app crash.
